Observe the weather and write a composition.

1. An essay on observing the weather during this period, the weather has changed greatly.

It was sunny the night before. If the sky is full of stars, it will be sunny the next day. It's sunny. Some people take their clothes to the balcony to dry, some people go for an outing together, and some people go to the park to exercise ... before it rains, it feels dark and stuffy.

It's raining, people who don't have umbrellas run home desperately, and those who have umbrellas quickly open them. In the event of a shower, even with an umbrella, it will become a "chicken soaking".

For our children, we generally prefer sunny days to rainy days; But flowers and trees still like rainy days. Finally, warm reminder: the weather is unpredictable. Everyone should learn to observe the weather and change clothes in time, but don't catch a cold and affect your study and life.

When I got up this morning, I saw that it was raining in Mao Mao outside the window and thought: Hey! It's time to open the umbrella stand again.

However, I have to go to school, so I have to bite the bullet and get to school. When I arrived at the school gate, I saw handfuls of "flower umbrellas" blocking the oncoming raindrops. The raindrops falling from the sky fell on the "flower umbrellas" and sang melodious songs. In this way, the naughty light rain kept jumping wow, wow, until noon, when it was tired of playing, it ran back to Mama Wuyun's arms. The weather is getting cloudy, and the shy grandfather Sun has been hiding in his home-the horizon. Time passed quickly, and then slipped away on Thursday.

On Friday morning, I just woke up from a sweet dream and a dazzling light flashed in front of my eyes. It turned out that the sun hung in the blue sky and baked the earth. Everyone smiled happily when they saw their long-lost grandson. What an unpredictable magician the weather is! Teacher's comment: The little author of this diary recorded his observation of the weather. The author introduced two kinds of weather in the article, namely rainy day and sunny day.

The article uses personification rhetoric, and the author uses his own imagination to vividly describe rainy and sunny scenes, which makes readers feel that the weather seems to be very individual. Articles are written in chronological order, so they are well organized.

This article shows the author's meticulous observation ability and good language expression ability. "Rain from the sky drops on the' flower umbrella' and makes melodious songs" is changed to "Rain from the sky drops on the' flower umbrella' and makes melodious songs".

"Naughty light rain kept jumping and laughing" was changed to "Naughty light rain kept jumping and laughing".

4. Observing the Weather Composition 500 words Today, I am lying on the edge of the grass again, forgetting the world and myself in infinite silence.

In front of my eyes, it has become bigger than ever, and the grassland has become a big forest. A little ant, walking around alone, found a crumb. I think it must be a clever cook. He came out to find something to cook. Now he has found it, but he can't move it. He turned and walked back to the cave. Soon, the ant chef brought out some porters. They worked together in Qi Xin to move the food in. They had a big dinner tonight! I seem to smell the rice fragrance of ants. I want to go in and share with them, but I'm afraid of scaring these elves.

The life of ants is also very regular. They are doing their own thing: the little ants are at school, the teachers are teaching, and their teachers and students are so serious and dedicated. When little ants go to school, their parents are working and going to work.

Jingle bell ... the school bell rang and the little ants all went home. When they get home, the little ants report their day's study to their parents, who may criticize them or praise them. A little ant who looks proud, I think it must have done well in the exam.

An ant robber fiercely stopped an ant resident, just as the ant policeman passed by and caught the ant robber. I think the ant police must be very happy because it has done a good thing for the people. Smoke rises in the farmhouse yard, and the barking of the puppy brings my heart back.

I want to take your hand to the ant kingdom for a walk. Today, I came to the ant cave with great interest and saw them bustling.

Ants stand in a row, ready to do exercises. Suddenly, the ants' team was in chaos and dispersed. They ran and ran and kept bumping left and right. A giant ant bumped into a petite ant, and the petite ant shed tears. What should I do? This petite ant can't climb any more. A large group of ants swarmed, picked up the petite ants and walked away. Their mouths kept comforting the little ants. The little ant was very grateful and said thank you.

My eyes followed the path of ants, and I saw the unity, mutual assistance and friendliness of ants. I have a lot there! I wandered all morning, and my heart didn't come back until Grandpa Sun laughed harder.

Seeing that they are so United and friendly, I am completely confused. How much wisdom is hidden in the ant's mind? How many qualities are ants worth learning? What makes them so United? I am completely immersed in the ocean of ants. The ant went home, and there was the sound of ants eating in the hole.

I, in this ocean of wisdom, have returned to nature (1). The grasshopper is "dressed in a green robe, with six thin legs, full of thorns on its legs and jumping three feet high". Hey hey, guess, what is this? I don't know, that's the "monarch" of the famous pest kingdom-Mr. Locust. Because I don't know much about it, I brought it back to study with its follower-grasshopper, and I gave it an interesting and unused name-"Green Train".

There are two flexible "antennas" at the front of the "green train", and there are two fake "clairvoyant eyes" under the antennas, which are sparkling and scary. Matching its eyes are those four terrible jaws, which move around as if to eat me.

There is a lovely "cherry three-petal mouth" hidden in the middle of this terrible chin. There is also a bell-shaped pattern on its abdomen, not to mention how weird it is. I think it might be used to scare people.

The biggest feature of the "green train" I haven't said yet is its six legs, four of which have a round sucker on each front leg, eight sharp claws, ten small suckers on each rear leg, and many thorns on the calf. If you look closely, it really looks like handfuls of saws. According to my mother, locusts and grasshoppers are small, but they are all super villains. They especially like to eat rice, wheat, sorghum, corn and other crops.

Where locusts have swept away, large areas of green land will become wasteland, crops will be eaten up and almost everything they can bite will be spared. This is really terrible. Hum, bad guy, now I will put you in the "detention room", go on a hunger strike and think about it, and see if you dare to do bad things again! (2) "Colorful Skirts" This time I will introduce you to a new protagonist. When you see it, you will definitely think of Cinderella in fairy tales.

It's wearing a dark gray dress, but it's just a cloak. As long as it spreads its wings, it will surprise you. It turns out that there is a colorful "dance dress" hidden inside! It is a mysterious visitor to my home-an unknown tramp, so I gave it a nickname-"colorful skirt". The colorful skirt looks like a butterfly, but I think it should be with locusts. Without kindness, it must be a "wolf in sheep's clothing".

The beautiful "dancing dress" of "colorful skirt" is really charming, but if you look closely at its head, you will find that it does not match its "honorific title": there are two jaws with small thorns under a pair of scarlet eyes! Hey hey, isn't that scary enough? There are many colorful dots embedded in its dancing clothes, including red, black, yellow and white, which are really beautiful in the dark blue background, so as long as other insects pass by, it can't wait to show off its "dancing clothes". But at the same time, he is so stingy. Listen, I haven't seen enough. He has packed his dancing clothes. Hey! I have no choice.

But don't worry, I'll tell you another little secret-"girl in colorful skirt" can't fly with wings, but usually she just jumps. Ha, you see, it is not happy now, and it is still worrying about it. (3) After reading the title of "Jumping Bean", everyone must want to know what "Jumping Bean" is, right? Um ... not another ... mystery visitor, is it? Haha, yes, it's already the second guest, who followed me when I was playing on the mountain.

Jumping beans have an inverted triangle body and green fur. Just like the colorful skirt of the last mysterious visitor, the coat is inconspicuous, but the shirt inside is very beautiful. Its shirt is red on both sides and blue and white lace in the middle.

Interestingly, "tiaodou" is still a veritable "small".

5. In the fifth grade Nature, some birds are singing and flowers are fragrant, and the spring is beautiful; Some xiao-he is hot and sharp in the scorching sun; Some are fruitful, and the autumn wind is cool; Some are snowing heavily and the wind is biting. Nowadays, Miss Winter has quietly replaced Miss Sentimental Autumn and is coming to us. ...

In the morning, my mother and I walked into the nature park together. "Wow!" You see, the frost makes the grass white everywhere, like a big cotton blanket spread on a large grass for fear of catching cold.

When you take a closer look, the frost is like snow, crystal clear, white inside and shining with golden light in the morning light, which is particularly beautiful. My little hand can't help touching it gently, and it feels very cold, but the frost seems to have disappeared shyly. The nose couldn't help but gather together, and a cool breeze sucked in. Suddenly the whole person relaxed, just like a golden cicada with its shell off. I couldn't help licking the tip of my tongue, just like tasteless ice cream, snow-white "cool Dan"

Although there is no heavy snow here, this boundless "frost" really adds a bit of "ice crystal world" flavor to the park!

How did this beautiful and cool cream come into being?

When I consulted the encyclopedia, I found the following results:

When hot air touches the surface of a cold object, the air will cool down, and when the water vapor is supersaturated, the excess water vapor will precipitate. If the temperature is lower than 0℃, excess water vapor condenses into crystals on the surface of the object, which is frost.

After the sun rises, the frost will melt, but it can last all day in cold weather or shady places.

In addition to frost, there are other beautiful natural phenomena waiting for you to go into nature to observe, and endless mysteries waiting for you to explore!

Yesterday morning, it began to rain in Mao Mao, and it was very cool. Little raindrops, like broken beads, are crystal clear. Naughty raindrops make the earth spotless and the flowers bright. What a diligent baby.

After eating a delicious lunch, I looked at the sky at the door. "Hey, the rain has stopped." . I hurried to the yard to play. Suddenly, I saw a ray of sunshine on the ground and looked up. The sun is out.

I shouted happily that the sun was shining brightly and the water on the ground was almost sucked dry. In the evening, I said to my parents, "The weather today is really bad. It rains for a while and sunny for a while. " Hearing this, mom and dad began to laugh. Dad said: "The weather is so bad, we must protect the earth in the future, otherwise, we may still live in the water."

I was very scared after hearing this, and said to my father, "I know, and I will definitely protect my motherland in the future." Students, do you know? We must protect this city in the future.

7. Observing the weather phenomenon 290 words My family has a lovely little white rabbit. His name is Beibei.

Its hair is as soft as a mass of white satin, thin and dense, and it looks like wearing a white fur coat. In the bright sunshine, it looks like a pile of sparkling white cotton balls, very beautiful! The chubby tail is hidden in the fluff, and it is not easy to find it if you don't look carefully. Its head is very small, and its two long ears stick to its head like two big fans. As long as there is any movement, those ears will keep swinging back and forth. Its eyes are particularly beautiful, the size of a small glass ball, and the red light is shining, just like a ruby embedded in white jade; It also has a lovely three-petal mouth, two on the top and one on the bottom. With two front teeth in his mouth, he bites badly; There are several thin beards on both sides of the mouth, which always make those two long ears stand straight and look proud.

Its front legs are short, its rear legs are long and powerful, it often bends, it jumps when walking, and it squats motionless on the ground, like marshmallows and snowballs. I made a home for the little white rabbit, put it in, and it jumped left and right, as if it were sweeter than honey. White rabbits like cabbage and radish best. Whenever I throw grass at them, it always dances with joy and greedily eats grass. It also made a "tut tut tut" cry, as if to say to me, "Thank you, this tender grass smells good!" After eating the grass, they lie down happily and close their eyes peacefully.

I love you-white rabbit, you are so full of vitality, so innocent and lovely! You brought endless happiness and reverie to my childhood.
